To all whom i mei/ i; concern.'

Be it known that l, vifi/linnen J. lliniiiiiinny :i citizen of the'United States of nieiicii, residing it Hartford, in the county of Tiereford sind State of Connecticut, have iiivontccl new :ind usefullmpi'oveinents in Drive-Chains, oi'f'wliicli tlie follcwing is zispecilication.

This inif'ention relates to drive-chains, und the objectief tlieinvention fully set forth in the follow/nig,` specification :intlillusti'zlieil in the accompanying (leanings, in `\.iliicl1,-

Figuie l is Li plan View of e puit of e. chain in which the invention isembodied. Fig is :i side elevation ot' the 'clniin shown in 1. Fig. 3 isa cross section of tlie cli-ein taken on the line 3-3, Fig. l, and il isan isometric View of ceitiiin associated parts of the eliiiiii shown inseiiaiii'eted lation.

Referring to the ili'ziwings, a indicates one of the sidepliites of thecliziin, and one o the connecting plates, the laitier serving topivotzilly connect two sitie plates, iis shown in Figs. l. und 2particularly, by ineens of the pins c ivliicli extend through holes inthe ends of both the side plates sind tl'ie connecting plates the endsoi which oveiliip the ends of tlie Side plates. ln @zich of 'the holesin the side plates t through Wliicli-tlie'piiis c pass, is tightlytilted ii bushing al, tlie length of which is oncflielf tlie width oitthe chain, and on these bushings iiie lo iitctl the link nienibei's eand f in the oitlei shown Fig. l, c indicating tliose Wliieli iiieiittefl ovei` the two bushings i in the suine side plate, :inil iliosewhich iiie 'ittefl ovei one bushing in euch of two side plates placedend to enil.
